I keep failing test cases for a method that finds the shortest distance using dijkstras algorithm can someone fix it$.$ private void findShortestDistance$()\{$

$//$ Initialize the shortest distance map

shortestRoutes.put$("$Westside$",$ new Station$("$Westside$",0))$; $//$ Set distance to Westside as $0$

$//$ Set distance to other stations as infinity $(\backslash$infty $)$

for $($String city : stations.getKeys$())\{$

if $(!$city.equals$("$Westside$"))\{$

shortestRoutes.put$($city$,$ new Station$("$Unknown$",$ Integer.MAX$\_$VALUE$))$; $//$ Set source station to "Unknown"

$\}$

$\}$

$//$ Initialize stack for stations to visit

Stack toVisit $=$ new LinkedListStack$<>()$;

toVisit.push$("$Westside$")$;

$//$ Set to keep track of visited stations

Set visited $=$ new HashSet$<>()$;

$//$ Main loop for Dijkstra's algorithm

while $(!$toVisit.isEmpty$())\{$

$//$ Get the current station from the stack

String currentStation $=$ toVisit.pop$()$;

$//$ Skip if station has already been visited

$//$ Mark current station as visited

visited.add$($currentStation$)$;

$//$ Get neighbors of the current station

if $($neighbors $==$ null $||$ neighbors.isEmpty$())\{$

System.out.println$("$No neighbors found for station: $"+$ currentStation$)$;

continue;

$//$ Loop through neighbors

for $($Station neighbor : neighbors$)\{$

int currentDistance $=$ shortestRoutes.get$($currentStation$).$getDistance$()$;

int distanceToNeighbor $=$ neighbor.getDistance$()$;

int newDistance $=$ currentDistance $+$ distanceToNeighbor;

$//$ Check if the new distance is shorter

if $($newDistance $<$ shortestRoutes.get$($neighbor$.$getCityName$()).$getDistance$())\{$

$//$ Update shortest route with the correct source station

$//$ Add neighbor to stack if it hasn't been visited
